Just re-read: Tactical Pistol Shooting: Your Guide to tactics that Work by Erik Lawrence, 2005, 0896891755.
Fantastic book. The best book on pistol shooting I have found. Lawrence is succinct with his instructions and the illustrations are numerous and well-done. Illustrations are essential in an instructional book like this and the photos (not line drawings!) are well lit, clear and focused, and taken from a variety of views. Good review information for a middling, no money for practice ammo, IPSC shooter like myself.
Lawrence covers drills and training exercises while also giving excellent pointers. Main chapters cover shooting positions, malfunctions, reloading, marksmanship, low-light shooting, shooting while wounded, and ends with a very comprehensive list of shooting schools.
